to improve the specificity of biochemical markers of myocardial infarction (mi) a method to measure cardiac troponin-i (ctn-i) was developed. ctn-i is a protein unique to cardiac muscle and is released after mi. consecutive 150 patients admitted to the coronary care unit was studied. value of ctn-i was determined in all samples. ctn-i concentration in the mi patients group was increased compare...

muscle tissue, skeletal muscle as well as cardiac muscle, is commonly affected in mitochondrial disorders. one explanation for this observation is that muscle tissue has a high-energy demand and therefore is more sensitive to a deficiency of mitochondrial energy production than some other tissues. in mitochondrial disorders, skeletal muscle tissue may be affected primarily by defective respirat...

background: hand grip strength (hgs) is a reliable indicator of peripheral muscle strength. although, numerous studies have investigated the strength of hand grip; little attention has been given to coronary artery disease (cad) patients, exploring the relationship between hgs and myocardial oxygen consumption (mvo2) index. the current study aimed to evaluate the interaction between hgs and mvo...

1. Cardiac muscle is a striated muscle, with a sarcomere structure much like that of skeletal muscle. It has small cells (as in smooth muscle), firmly connected end-to-end at the intercalated disks. 2. The action potential in cardiac muscle is long lasting compared to the duration of the contraction, preventing a tetanic contraction. 3. Under normal circumstances, cardiac muscle operates at len...
